siderable portion ot the periphery of the rolt. Rotary motion is imparted to the winding' beam 39 and roll i8 through a trainfot gears (not shown) 'in a well known or approved manner.

The fabric 19 is arranged to pass over rollers 45, 47 mounted in a rocking `frame Lili pivotedat 49' between the supports di), i-1. Thus it will be seen' that the Jfabric will pass troni the breast beam 2 over rollers 46, hla7 to the idler roller est thence around the winding roll /18 overtheidler-roller d5 and thence downwardly to be wound upon the winding,l beam 39.

The rocking framed?) is actuated' by means ot a cam 'Ohxed to spur-gear 51 mounted to rotate on a stud shaft 52 carried by a An angle lever 5at1pivoted onithe trame at 55 ispro- 'vided at onel endwith a truck roller 56 which engages the cam 50, while the other vend of the lever" 54 is -connected to an arm 57 depending 'from the rocking frame 48 by a link'58. Theroekingframe 48 may bV adjusted'in its oscillatory movement byl means ot thearm 57 having),` a series of holes :tor the reception of' apin 59 whic-h secures the link 58 to the arm. Motion is imparted to the cam and Spur gear 51 through a pinion 60 fast on a shaft 61 mounted in bearings carried bythe frame 1, and a spur gear 62 iXed-on the shaft 61y arranged to mesh with the spur gear 7 yoit the crankshaft 6.

It is desirous'that a predetermined amount ot pile warp threads 2O be withdrawn'trom thebeam 21, which amount is not returned to the beam, as in the case of the ground warp threads 11, and inv order to laccomplish this result the pile war-p beam 21 is provided with a ratchet 63 fixed to rotate therewith and series ofpawls 64 which are free to oscillate on a pin 65 tast to the trame 1, and arranged to engage the ratchet 68. rlhe beam 21 is also,` providedwith the usual and well known slip trict'ionfdevice'66, which will be readily understood by persons skilled in the art.

In operation'of the loom, power trom the motor 10 is applied through pinion 8, spur gear`7,and to the crank shat't 6 4to aotuate the lay 3,the patternv chain 38 and mechanism isv actuated in unisonwith the movement of the lay 3 `and by the usual well known mechanism; and wett shuttles (not shown) are passed between and-through the warp threadsinlthe usual manner by mechanism well known to those skilled in the art.

During the weaving` of the fabric the pattern chain-mechanism willv control the movement ot theheddles 16` so asto raise and lower the ground warp threads 11 and the pile warp threads 20 tor weaving the ground orbody of' theta-bric' and for the production ot the-standinglooped pile.

Lv'Fromf'the foregoing it vwill 4be seen` that VVground and pile warp threads and beaten up to a temporary position.v At this time, the

yram Oagainfactuates the levei1 541-, link 58, arm 57, frame A18, and roller 4:6 in the rearward `direction or toward the'breast beam '2, lthereby allowing ground warp threadsll to move rearwardly and be wound upon their beam 12 while the pile warp threads 'Q0 are retarded or arrested in their rearwarl movement by the ratchet 63 and pawls .Ga ot the pile warp beam Qi. :At the next succeeding movement of the lay 3,the number of ground wett; threads vpreviously woven willabe beaten tfowardithe tell 18, and since there is a certainamount oi' slack in the pile warp threadsQO between the number of ground wett threads and the tell 18, these pile warplthreadsl 2U will 'form a row ot loops rbetween the fell and ground wett threaus. After this `number of ground wett threads havebeenbeaten upto the tell, the cam50 willagain actuate the trame 48 with its roller. 17 through thelever 54, link 58 and arm 57, and thecycle of operation repeated.

It is obvious thaty various changes may be resorted to in the form, construction and arrangement ot' the several parts without departing from the spirit and scope of' my rinvention; and hence,` I do not Aintend to be limited to the particular embodiments herein shown and described except as they'may be includedinithe claims.
